STUDY OF UNSTEADY SHIP MOTION AT A LIMITED DEPTH
Experimental investigations of unsteady ship motion in shallow water have been carried out at the Institute of Hydromechanics AN UkrSSR. Large-scale models were towed through a gravitational-type research pool at various depths. The changes in resistance as a function of model speed during acceleration and consequent inertial path, starting from the instant of automatic removal of the driving force, were studied. A reduction in resistance during acceleration was noticed in the region of critical velocities. Formulas were obtained for the calculation of the instantaneous and average over-a-given-interval arguments for the value of the coefficient of added mass. In general, the work represents a search for approaches to further investigation
